3 Claims.

with guide grooves for the proper direction of jewels being set in such rollers.

An additional object of the invention is the provision of such a device having means comprised of plungers for facilitating the insertion of the jewels.

Another object of the invention is the provision of such a device having means whereby the rollers may be suitably heated prior to insertion of the jewels.

Other objects will in part be obvious and in part be pointed out as the description of the invention proceeds, and shown in the accompanying drawings, wherein there is disclosed a preferred embodiment of this inventive concept.

In the drawings:

Figure 1 is a front elevational view of one form of tool embodying features of the instant invention.

Figure 2 is a top plan view of the construction shown in Figure 1.

Figure 3 is an enlarged sectional view taken substantially along the line 33 of Figure 2.

Figure 4 is an enlarged perspective View of a constructional detail.

Similar reference characters refer to similar parts throughout the several views of the drawmgs.

Having reference now to the drawings in detail, the device of the instant invention is comprised of a base I0, and two uprights ll of substantial width, and each provided with a groove or channel I2 adjacent the top thereof, a jewelholding plate I3 being slidably mounted in the groove I2. The plate is provided with a plurality of parallel aligned channels [4, l5 and I6 of varying widths to accommodate jewels of various sizes, as will be explained hereinafter, and has adjacent one end thereof a guide plate I! provided with corresponding inverted channels, serving as securing means for a pluralit of plungers I8, I9 and 20, slidable respectively into grooves l4, l5 and I6. Each plunger is provided at its extremity with a hand knob 2|, and at its inner end is provided with an overhanging lip 22 adapted to overlie the fiat side of a jewel of conventional design, in order to securely hold the same in position in the groove during insertion in a roller, in a manner to be described more fully hereinafter.

Secured to the front of the apparatus in any desired means, as by screws 25, is a bar 26 provided with a series of cut-away portions 21, 28 and 29, in spaced relation and adapted to be aligned respectively with the grooves l4, l5 and I6, and in which are adapted to be positioned rollers to accommodate jewels 30 (see Figure 3) for insertion therein. Spring fingers 3| are suitably secured, as by rivets or screws 32, to the bar 26 adjacent each of the grooves 21, 23 and 29 and on opposite sides thereof, adapted to secure the roller in desired position. The bar 26 is provided with an extending portion 33 under which is adapted to be positioned a heating unit, such as an alcohol lamp, for raising the temperature of the bar 26, and correspondingly the temperature of the roller associated therewith to expand the apertures therein for the reception of jewels.

From the foregoing, the operation of the device should now be readily understandable. The plate I3 is first suitably slid back, and a roller 35 (see Figure 3) of any desired type, provided with an aperture 36 for the reception of a jewel, is seated in the appropriate channel or slot, in the illustration shown in Figure 3, the slot 29. The aperture 36 is then carefully aligned with the groove or channel I6, and the plate l3 slid back to overlie the inner portion of the roller 35 which has a shaft 4!] extending therefrom forming the rotating support for the roller in a watch, the spring fingers 3| positioned on both sides of each recess or slot 29 as shown in Figures 1 and 2, serving to hold the roller 35 firmly in alignment with the front of the tool. A jewel 30 is then positioned in' channel lfi and pin 20 arranged so that lip 22 overlies the fiat edge of the jewel. Jewel cement is then positioned in hole 36, and forward movement of pin 20 will cause jewel 30 to seat smoothly in aperture 36 with a minimum of difficulty and effort.

From the foregoing it will now be seen that there is herein provided an improved jewel-setting tool which accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.

I claim:

1. In a jewel-setting tool, a frame, a top plate mounted on said frame, said top plate formed with a jewel receiving groove thereon, a front bar secured to said frame and formed with a roller receiving recess in alignment with said groove in said top plate, spring fingers on said front bar for holding a roller in alignment with said groove, and a plunger in said groove for moving a jewel into engagement with the roller.

2. A jewel-setting tool comprising a frame, a

plate slidable on said frame and formed with a jewel receiving groove, a front bar on said frame and formed with a roller receiving recess in alignment with said groove, the forward edge of said plate engageable over said roller for seating the roller in said recess, and a plunger slidable in said groove for moving a jewel into engagement with the roller.

3. A jewel-setting tool comprising a frame, a

jewel supporting member slidable on said frame, a roller supporting member on said frame and formed with a roller receiving recess, means on said roller supporting member securing a roller thereon, said jewel supporting member engageable over a roller on said roller supporting member for seating the roller thereon, and a jewel 4 engaging member slidable on said jewel supporting member in alinement with the recess in the roller supporting member for moving the jewel into engagement with the roller.
